Two graphics cards of miner don't work
-
what is the specific model of the graphics card? If the graphics card supports the intelligent temperature control start stop technology, the temperature will not turn until it reaches 50-60 degrees
-
you can use gpu-z to detect the real-time temperature of the graphics card and see how much the temperature will turn. If the temperature reaches 50-60 degrees, it is normal
Notebook equipped with al graphics card, will automatically choose one of the graphics card (single display or centralized display) to work according to the running program, this is a normal phenomenon, it can also be considered to set the computer's default graphics card
here, take NVIDIA graphics card + integrated display as an example to introce the next switching steps:
1. Right click the blank space on the desktop to pop up the menu of options and find "NVIDIA control panel" in the menu

video card (graphics card) full name display interface card, also known as display adapter, is one of the most basic configuration and most important accessories of computer. As an important part of the computer host, the graphics card is the equipment of digital to analog signal conversion, and it undertakes the task of output display graphics
the graphics card is connected to the main board of the computer, which converts the digital signal of the computer into an analog signal for the display. At the same time, the graphics card still has the ability of image processing, which can help the CPU work and improve the overall running speed. For those engaged in professional graphic design, graphics card is very important. Civil and military graphics chip suppliers mainly include amd (ultra micro semiconctor) and NVIDIA (NVIDIA). Today's TOP500 computer, including graphics card computing core. In scientific computing, graphics card is called display accelerator<
core graphics card
core graphics card is the new generation graphics processing core of Intel procts. Different from previous graphics card design, Intel integrates graphics core and processing core on the same substrate to form a complete processor by virtue of its advanced process and new architecture design
the design integration of intelligent processor architecture greatly reces the data turnover time among the processing core, graphics core, memory and memory controller, effectively improves the processing efficiency and greatly reces the overall power consumption of the chipset, helps to rece the size of the core components, and provides a larger choice space for the design of notebook, all-in-one machine and other procts
It should be noted that the core graphics card is different from the traditional integrated graphics card. There are two kinds of graphics solutions for notebook platform: "independent" and "integrated". The former has a separate graphics core and independent video memory, which can meet the complex and huge graphics processing needs and provide efficient video coding applications; The integrated graphics card integrates the graphics core on the motherboard in the form of a single chip, and shares part of the system memory as the display memory dynamically, so it can provide simple graphics processing ability and smooth coding application Compared with the former two, the core graphics card integrates the graphics core into the processor, which further enhances the efficiency of graphics processing, The three chip solution of "processor + South Bridge + North Bridge (graphics core + memory control + display output)" in the integrated graphics card is simplified to a al chip mode of "processor (processing core + graphics core + memory control) + motherboard chip (display output)", which effectively reces the overall power consumption of the core components and is more concive to extending the life of the notebookadvantages of core graphics card: low power consumption is the most important advantage of core graphics card. Due to the new simplified architecture and integrated design, core graphics card has more excellent control over the overall energy consumption, efficient processing performance, greatly shorten the computing time, and further rece the energy consumption of the system platform. High performance is also its main advantage: core graphics card has many advantages of technology, can bring sufficient graphics processing capacity, compared with the previous generation of procts, its performance progress is very obvious
the core graphics card can support DX10 / Dx11, sm4.0, opengl2.0, and full HD MPEG 2 / h.264/vc-1 format decoding technologies. The dynamic performance adjustment to be added can greatly improve the processing capacity of the core graphics card, making it fully meet the needs of ordinary users
disadvantages of core graphics card: the price of CPU for core graphics card is usually not high, and the low-end core graphics card is not suitable for large-scale games
integrated graphics card
integrated graphics card is a component that integrates the display chip, memory and related circuits on the motherboard; The display chip of integrated graphics card has its own, but most of them are integrated in the north bridge chip of motherboard; Some integrated graphics cards on the motherboard also have separate memory installed on the motherboard, but their capacity is small. The display effect and processing performance of the integrated graphics card are relatively weak, so it is not possible to upgrade the hardware of the graphics card. However, the potential of the display chip can be tapped by adjusting the frequency of CMOS or brushing in the new BIOS file to achieve software upgrade
the advantages of integrated graphics card are: low power consumption, low heat, and the performance of some integrated graphics cards is comparable to that of entry-level independent graphics cards, so there is no need to spend extra money to buy independent graphics cards
disadvantages of integrated graphics card: its performance is relatively low, and it is fixed on the motherboard or CPU, so it cannot be replaced. If it has to be replaced, it can only replace the motherboard
independent graphics card
independent graphics card refers to the display chip, video memory and its related circuits are made on a circuit board independently, and exist as an independent board. It needs to occupy the expansion slot of the motherboard (ISA, PCI, AGP or PCI-E)
advantages of independent graphics card: it has a separate video memory, generally does not occupy the system memory, and is much more advanced than the integrated graphics card in technology, but its performance is certainly not inferior to the integrated graphics card, so it is easy to upgrade the hardware of the graphics card
disadvantages of independent graphics card: the power consumption of the system is increased, and the calorific value is also large, which requires extra money to buy graphics card, and at the same time (especially for notebook computers) takes up more space
e to the different performance of graphics cards, the requirements for graphics cards are also different. Independent graphics cards are actually divided into two categories, one is entertainment graphics cards specially designed for games, and the other is professional graphics cards used for drawing and 3D rendering
when the temperature does not reach the specified temperature, it will not rotate
it is detected when it is turned on, so it will turn twice
you can play games and see if it rotates normally when the temperature rises.
try playing a big game, or running points, to see if the video card fan will turn
(adopted by watchtower owner)
you can try playing games. Will it turn
if you play the game, you don't turn. That's as tragic as I am
a fan is broken
